The first thing we did was click on a new RMarkdown document, gave it a title, and gave it an author
Then we added: code_folding, df_print, theme, highlight, toc, toc_depth, and number_sections to the YAML
When using toc, make sure to start with H1 headers, which are used to generate the toc
ctrl + alt + i will create a code chunk
We added {.tabset .tabset-fade .tabset-pills} to the H1 headers.
